Inventor: KUBOTA TOMOHIRO
IPC: A63F7/02
Filed: 2021-11-16
Abstract: To provide a novel game machine.SOLUTION: A frame control board 50 manages a difference in the number of balls. The difference in the number of balls is calculated from the number of prize balls transmitted from a main control board 30, and the number of shot balls and the number of foul balls managed by the frame control board 50. The frame control board 50 transmits the difference in the number of balls to the main control board 30 by commands. A value obtained by dividing the difference in the number of balls by 1000 is transmitted to main control by commands (is transmitted by a value ranging from 00 to 96). The value 96 assumes a case when the difference in the number of balls exceeds 96000 after completion of a big win or after completion of a small win although a difference-in-the-number-of-balls restriction device operation condition is established during the big win or the small win. The main control board 30 manages difference-in-the-number-of-balls restriction device operation. When a value of a command received from the frame control board 50 reaches a prescribed value (95), a difference-in-the-number-of-balls restriction device is operated. During the big win or the small win, the difference-in-the-number-of-balls restriction device is operated after completion of the big win or the small win. The main control board 30 stops a game when the difference-in-the-number-of-balls restriction device is operated (a game stop state is started).SELECTED DRAWING: Figure 2
